Previfem Dosing

While Previfem is relatively easy to use, there are some standard dosing guidelines to be aware of before using this birth control pill. If you are starting it for the first time, you can do so on the first day of your period or the first Sunday after your period starts. Be sure to take one Previfem tablet daily, at the same time each day.

Previfem Dosage: An Introduction

Previfem® (norgestimate/ethinyl estradiol) is a birth control pill that is a generic version of Ortho-Cyclen®. There is only one standard dose of Previfem. As always, do not adjust your Previfem dose unless your healthcare provider specifically instructs you to do so. Although Previfem is very effective when taken correctly, not taking Previfem as directed significantly increases the risk of unintentional pregnancy.

Previfem Dosing Basics

There are two different standard ways to start Previfem for the first time. You can start it either on the first day of your period or on the first Sunday after your period starts (even if you are still having your period). It is thought that starting on Sunday may decrease the chance that you will have your periods on the weekends, although this does not work for all women. If you start Previfem on the first day of your period (a "day 1 start"), you do not need any backup contraception. If you choose a Sunday start, you need to use a backup method of contraception (such as condoms) for the first week. If the first day of your period happens to be on a Sunday, treat this as a day 1 start (no backup needed).
There may be other ways to start Previfem (other than a day 1 start or a Sunday start); be sure to follow your healthcare provider's instructions carefully if you start Previfem in a non-standard way.
Starting at the beginning of the pack, take one tablet daily at the same time each day. Each pack will last for 28 days (four weeks). After you finish one pack, immediately start a new one the next day. Do not wait any days between packs (this may take a little planning, since you will need a new pack on hand). The first 21 tablets contain the active ingredients. The last seven tablets contain no active ingredients. During this last week, your body gets a little break from the hormones, allowing you to have a period.
